“…A measurement consists of determining the net count rate due to the 6 Li(n,a) 3 H reaction from the bare detector, from the detector covered with a cadmium shield and from the detector at the center of each of five polyethylene spheres of the following diameters: 3, 5, 8, 10, and 12 inches. The net count rates are used in an iterative unfolding code to solve the Fredholm integral for neutron energy spectrum and flux (Endres et al 1981).…”

“…The predominance of neutrons with energies less than 100 keV caused the dosimeters to indicate that more dose equivalent was received than actually was received. The reasons for that 'high response' lie in the energy dependence of the response of the TLD and in the choice of calibration sources (Endres et al 1981;Cummings et al 1983).…”

vi Because the TEPC measures neutron absorbed dose directly, is more straightforward in analysis than the multisphere technique and because the energy dependence of remmeters leads to an over estimation of neutron doseequivalent rates in containment by a factor of 1.71 on the average, the authors concluded that 1) the TEPC is the superior technique for accurate determination of neutron dose-equivalent/rate inside containment of nuclear power plants; 2) that results from remmeters currently in use and similar to the one evaluated herein be adjusted to account for energy dependence or that the remmeters be calibrated using a moderated neutron source which provides response similar to the response to neutrons found inside containment of commercial nuclear power plants, and 3) that the TEPC not be used to measure absorbed dose from photons at this time. Further, when a miniaturized portable version of the TEPC is available, it should be evaluated as to its application to dose equivalent determination inside containment of commercial nuclear power plants thereby verifying the appropriateness or inappropriateness of the technique for routine neutron dose equivalent monitoring. vii CONTENTS ABSTRACT SUMMARY INTRODUCTION INSTRUMENT DESCRIPTIONS TISSUE EQUIVALENCE

“…Not listed are the responses of commercial dosimeters evaluated by PNL in Subtask A and Subtask B of 11 Neutron Dosimetry at Commercial Nuclear Plants .. (Endres et al 1981 andCummings et al 1983). The similarities between the commercial albedo dosimeters and two DOE-laboratory developed albedo dosimeters are such that the general conclusions reached for the latter are valid for the former.…”
